main reason has fluctuated but was the third most common reason in 2019. 75% of lawn and garden owners fertilize their lawns at least once per year. Among those who fertilize once a year, 14 percent fertilize in the spring and only six percent fertilize in the fall. This suggests that there is room to educate residents of Northern Virginia that fertilizing in the fall is better for local waterways. About half of the respondents reported using an herbicide to treat weeds in their lawn or garden. Among those who fertilize their lawn, 75 percent have never had or were not sure if their soil had been tested for fertility or pH and fifty five percent reported using a slow release fertilizer. In a new question for 2018, after reading a description of a rain barrel, rain garden, and conservation landscaping, respondents were asked if they had implemented these features at their home or had heard about them. Six percent reported having a rain barrel, while two percent reported having a rain garden, and seven percent reported having conservation landscapes in their yard. This indicates there is a significant opportunity to continue to promote these practices to homeowners. Consistent with past years, the majority of respondents take their vehicle to a service station for oil changes (83%) or take used oil to a gas station or hazmat facility for recycling (8%). Approximately four percent of Northern Virginians reported storing used motor oil in their garage, placing it in the trash or dumping it down the storm drain, sink or on the ground.

Fiscal Year 2019 ANNUAL REPORT: RainSmart Program for the City of Falls Church

To the: City of Falls Church, Va. From the: Falls Church Village Preservation and Improvement Society

September 2019

RainSmart Program Report: Fiscal Year 2019

In January 2018, the Village Preservation and Improvement Society (VPIS) and the City of Falls Church entered into a Memorandum of Understanding (MOU) providing for a RainSmart program to help manage stormwater in the City of Falls Church. VPIS provided an annual report of RainSmart program activities during fiscal year 2018 (i.e., from January to June 2018) in October 2018. This report provides a summary of activities from July 2018 to June 2019.

RainSmart Program Overview and Accomplishments

The purpose of the RainSmart program is to promote practices that soak rainwater into the ground on-site to prevent flooding and protect the quality of local streams and the wider Chesapeake Bay watershed. Capturing rainwater on-site and letting it soak into the ground reduces the flow of stormwater to drain pipes and reduces the high-volume flushing that is damaging to local waterways. Soaking rainwater into the ground also prevents stormwater from collecting pollutants as it runs off from streets, parking lots, and other impervious surfaces and discharge of these pollutants to streams. Key elements of the Program include: • Public education and outreach; • Rain Barrel Project Grants; and • Rain Garden and Landscape Conservation project grants.

Public Education and Outreach: During the six months of fiscal year 2018 covered by the MOU, VPIS focused on the initial launch of the program and building public awareness of the assistance available through the Program. Some key activities during this period included: • Cooperation with the City of Falls Church to draft a Press Release describing the Program (see attachment 1); • Maintenance and updating of web pages describing the RainSmart Program on the VPIS website, including background information and applications for grant assistance (http://www.vpis.org/environment/rainsmart-program/); • Drafting an article on the Program published in the VPIS member newsletter, the Village Way; • Placement of a classified Ad concerning the RainSmart program in the News Press; • Promotion of the Program in other forums including the City of Falls Church Farmers’ Market; • Printing of flyers describing the Program for use at meetings and other forums; and • Outreach via email to landscape contractors in the area describing the Program.

Rain Barrel Project Grants: The RainSmart Program promotes the purchase and installation of rain barrels though both stormwater education and financial assistance in the purchase of rain barrels. The Program provides grants of $50 per rain barrel to support purchase and installation of up to two rain barrels.

2

Applications for funds to reduce the cost of rain barrels are available on the VPIS website. On receipt of a completed application meeting program requirements, applicants are notified of project approval. The applicant is then able to purchase up to two rain barrels and, after installing the rain barrel(s), provides a photo of the installed rain barrel(s). The Program then provides the applicant a check for $50 per installed rain barrel. Rain Garden and Landscape Conservation Project Grants: The RainSmart Program provides grants to Falls Church residents, non-profit organizations, and businesses to support the design and installation of rain gardens and for installation of landscape conversion projects to replace lawns with plantings that retain stormwater. Grants are for not more than $1,500 or 50% of the total project cost, whichever is less.

The application for rain garden grants is available on the VPIS website. Interested parties may submit an application for approval, including an initial cost estimate. If the application is approved, the applicant proceeds to install the project and provide photos and receipts documenting the project. Based on this information, the Program provides the applicant a check in the appropriate amount.

Lessons Learned RainSmart program managers learned several lessons in the initial startup phase of the Program:

• It is important to have strong communication with landscape contractors concerning program requirements to avoid confusion and assure that costs of rain gardens are kept separate from other landscaping work that is part of a larger project. • The Program managers need to make clear that projects that include landscaping practices that do not support effective stormwater management may be a basis for disapproval of a grant for a rain garden or conservation landscape project that is part of a larger project. • Several rain barrel projects involved purchase of rain barrels from the Northern Virginia Soil and Water Conservation District at rain barrel events. More advanced publicity of these events is likely to prompt additional rain barrel grant requests. • Project applicants are generally not aware of the potential for credits under the City stormwater fee credit program and more effort should be made to explain the credit options. • The $1,500 cap on rain garden and conservation landscape projects limits grants to a small part of the prevailing cost of installed projects. It may be appropriate to increase this cap at some point in the future.

Summary of Projects During fiscal year 2019 (July 2018 to June 2019) the RainSmart Program provided grants for two conservation landscape/rain garden projects and four grants for a total of 7 rain barrels.

3

The project grants included:

1) A grant to Arron Steigerwald of 117 West Westmoreland Road in Falls Church for a conservation landscape project to reduce stormwater runoff and control water pollution in the amount of $400; and 2) A grant to Eric Hammerschmidt of 113 Spring Street in Falls Church for a conservation landscape project to reduce stormwater runoff and control water pollution in the amount of $1,500.

Rain barrels projects included:

1) Anna Bysfield; 1112 Jackson Court, Falls Church; 2 rain barrels; 2) Jeanne McHugh, 504 North West Street, Falls Church; 1 rain barrel; 3) Susan Martin, 312 Lincoln Ave, Falls Church, 2 rain barrels; 4) Chris Thompson, 406 North Van Buren St., Falls Church, 2 rain barrels.

Selected project photos are attached.

Summary of Maintenance Activities Email addresses from rain barrel grant applicants are now entered into a group email that will be used to provide periodic reminders and tips to owners of rain barrels on maintenance and operational topics.

Grants for Homeowners to Reduce Stormwater Pollution in Falls Church

The Falls Church Village Preservation and Improvement Society (VPIS) is making grants to City of Falls Church residents for projects to reduce stormwater runoff. Grants are available for projects to install rain gardens or conservation landscapes and for purchase of rain barrels to store rain water.

The grants are part of the RainSmart Program implemented by VPIS with support from the City of Falls Church. The Program is intended to help City of Falls Church residents implement practices, such as rain barrels and rain gardens, that help rainwater soak into the ground on- site to prevent flooding and protect water quality locally and in the wider Chesapeake Bay watershed. The Program also includes public information and outreach programs to promote stormwater management.

An easy step that local residents can take to manage stormwater is to install rain barrels to catch runoff from roofs. Under the RainSmart Program, City residents can apply for grant funds for up to two rain barrels with a limit of $50 for each barrel. Some residents may want to use this grant at rain barrel workshops in the region sponsored by the Northern Virginia Soil and Water Conservation District (see: https://www.fairfaxcounty.gov/soil-water-conservation/rain- barrel). Workshops are scheduled for March 10 and 30, April 5 and 6, and May 25. Residents may apply for rain barrel grants throughout the year and have the option of applying for a grant to support purchase of rain barrels from a commercial source. Residents are responsible for installing and maintaining rain barrels.

Another opportunity to improve local stormwater management is to install a rain garden that is designed to help rain water soak into the ground and help reduce high volumes of runoff that

5 carry sediment, nutrients, and other pollutants into local streams. Under the RainSmart Program, City residents can apply for grant funds to cover up to 50% of the cost of a project or $1,500, whichever is less. Grants are also available for landscape conservation projects that have Page 2 stormwater benefits. These projects need to be designed and installed by contractors approved by the RainSmart Program. Funds for both rain barrel and rain garden grants are limited. Applications for rain barrels will be considered on a continuing basis until available funds for the year are committed. Applications for rain gardens and conservation landscapes require some initial design and are due by May 3. Applications will be considered and funded giving priority to projects with the greatest stormwater benefits to the community. Applications received after the due date will be considered if funds are available. For more information about the RainSmart Program and for rain barrel and rain garden applications, go to: http://www.vpis.org/environment/rainsmart-program/. If you have questions about the RainSmart Program, send an email to [email protected].

Mr. Chris Swanson, P.E. State MS4 Stormwater Management Engineer VDOT- Location& Design Division 1401 East Broad Street Richmond, Virginia 23219

Dear Mr. Swanson:

Pursuant to 9VAC25-890, Virginia’s Municipal Separate Storm Sewer System (MS4) Management Program, the purpose of this letter is notify you, as a downstream regulated MS4 which the City of Falls Church’s system is physically interconnected with, of our recently updated outfall map showing existing outfalls and stormwater infrastructure that may impact a shared water body.

The City of Falls Church is within the Four Mile Run watershed (HUC Code: PL25, Cameron Run watershed (HUC Code: PL26), and Pimmit Run Watershed (PL24). Stormwater runoff from approximately 2.23 square miles of land characterized as suburban residential and commercial is conveyed through a series of pipes and open streams and ultimately into both Arlington County via Four Mile Run and Fairfax County via Tripps Run. The enclosed map demonstrates the locations of the interconnections. Stormwater flows through a portion of the VDOT system prior to reaching Arlington or Fairfax Counties.

If you have any concerns or questions about the connections please don’t hesitate to contact me. I can be reached at 703-248-5026 or via email [email protected] .

Sincerely,

Alan R. Dalton, P.E.
